Range anxiety, charging speed and sticker price are the three factors that most often decide whether a buyer chooses an electric vehicle — and all three trace back to a single component: the battery. Designing that battery well means balancing electrical engineering, chemistry and materials science against real constraints of energy density, thermal behaviour, charging speed and safety.

Arab British Fellowship Training Academy built this course to take participants inside that balancing act. Rather than treating EV batteries as a black box, it breaks down the chemistry, the components and the engineering decisions that separate a competitive battery pack from an underperforming one, drawing on current industry practice and emerging trends.
